My view of the winners and losers in Tuesday night’s Democratic debate is pretty much the same as what I’ve seen from other observers. Hillary Clinton won with a strong, polished performance (and was likable enough). Bernie Sanders was uneven but had his moments. And Martin O’Malley emerged as the only real alternative to the two front-runners, as Jim Webb fizzled and Lincoln Chafee popped.

So let me turn instead to the biggest loser of the debate: CNN, which for whatever reason just can’t seem to get its act together. Moderator Anderson Cooper is a smart, authoritative presence, but during the debate he was both too authoritative and too present. He interrupted constantly. Every candidate’s answer, it seemed, played out against a backdrop of Cooper trying to get him or her to stop. Sometimes a strong hand is needed. But politics ain’t beanbag, as Mr. Dooley instructed us. Let them mix it up.
